MITRE ATT&CK

T1059.001 PowerShell T1566.001 Spearphishing Attachment T1140 Deobfuscate/Decode Files or Information

The PDF file exhibits characteristics of malicious intent, including obfuscated content and an embedded binary file. The ClamAV heuristic 'Heuristics.PDF.ObfuscatedNameObject' strongly indicates malicious obfuscation. The presence of an embedded file, 'embedded_file_obj0001.bin', suggests a delivery mechanism for a secondary payload. The XFA form and embedded file heuristics further support the likelihood of a malicious document.
